  • Patent number: 5523451
    Abstract: Organic carbonates which contain at least one aromatic ester group can be obtained continuously from carbonates, which contain at least one aliphatic ester group, and a phenolic compound in the presence of a transesterification catalyst known per se in that the reaction is carried out in a bubble column reactor or in a cascade of at least two bubble column reactors in such a way that the phenolic compound is metered into the first bubble column and the carbonate containing at least one aliphatic ester group is metered into each individual bubble column, but preferably only into the last bubble column. The carbonate containing at least one aromatic ester group is taken off in the liquid state from the last bubble column. Volatile reaction products, for example eliminated alcohol or a dialkyl carbonate are taken off at the upper end of each individual bubble column, preferably at the upper end of the first bubble column.

  • Patent number: 5523238
    Abstract: A method for determining a platelet function in a primary hemostasis is provided in which a blood sample or a platelet containing fraction thereof is introduced into a vessel having a flat bottom which has an inner surface covered with a substrate capable of inducing platelet adhesion thereto and aggregation such as ECM (extracellular matrix). Preparation is then rotated inside the vessel, and consequently shear forces develop on the surface which bring to adhesion an aggregation of the blood platelets to the surface. Morphological parameters of blood aggregates are then determined.
